It’s not unusual for construction projects to require the skills of a wide range of technicians and trade professionals. Projects involving a structure’s water system are no exception. Both plumbers and pipefitters play key roles in ensuring that plumbing is safe, functional, and compliant with applicable laws and building codes.

Are you interested in becoming a plumber or pipefitter? You should know what these two types of trade professionals do so that you can pursue the career that makes sense for you. Here is some basic information about the difference between plumbers and pipefitters.


What Does a Plumber Do?

Plumbers are responsible for the overall function of plumbing components in residential and commercial settings. They are typically permitted to install, maintain, repair, and alter plumbing equipment and parts, and their primary goal is to manage water supply, drainage, and waste disposal systems.

A plumber may work on new construction or answer calls for maintenance and repairs, or both. Often, their daily tasks involve diagnosing plumbing problems and addressing common issues like clogged drains or leaky pipes.

With specialized training, many plumbers are also qualified to install, maintain, and repair gas lines. All plumbers are required to conduct their work in keeping with local, state, and federal plumbing codes and regulations.


What Does a Pipefitter Do?

Pipefitters also work on piping systems, including plumbing and gas lines, but they perform in a specialized capacity. These trade professionals focus on the installation, maintenance, repair, and alteration of high-pressure piping systems used for industrial and, sometimes, commercial purposes. They don’t typically work in residential settings.

The chemical, steam, and gas systems for factories, power plants, and other industrial concerns carry heightened risks for injuries related to heavy equipment and hazardous materials. Pipefitters must therefore prioritize their safety and that of others around them in their daily work.

Additionally, pipefitters must develop specific skills related to their job. They know how to read engineering plans and blueprints and are trained in cutting and welding pipes. Along with following strict safety protocols, they must understand and comply with applicable laws and building codes.


Qualifications for Plumbers and Pipefitters

Most states have implemented licensing requirements for skilled trade professionals, including plumbers and pipefitters. Only a handful lack statewide licensing systems. In such cases, licensing is usually managed at the local level.

Full licensure requires education, experience, or a combination of the two. Typically, the path starts with a journeyman license, followed by a master license.

Many plumbers and pipefitters prepare for licensing through state-approved apprenticeship programs. Insurance and bonding may be required, and license applicants must pass either state-administered or equivalent national exams.


Preparing for Professional Exams

The best way to pass state licensing exams on the first try is with a program designed by and for working professionals. Look for 24/7 online access that allows you to learn at your own pace, along with a no-pass, no-pay policy.
